简介
The HSP70/HSPA1B protein is an important molecular chaperone that ensures proteome integrity by protecting against stress, aiding in protein folding, activating proteolysis, and regulating protein complex assembly. It remains accurately folded through the ATP cycle and co-chaperones such as HSP40, BAG1/2/3, HOPX and STUB1. HSP70/HSPA1B Protein, Human (SF9, His) is the recombinant human-derived HSP70/HSPA1B protein, expressed by Sf9 insect cells , with N-His labeled tag.

Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
Storage & Shelf Life

Protein Description
HSP70, particularly the HSPA1B isoform, is a highly conserved heat shock protein crucial for cellular stress response and protein homeostasis. It acts as a molecular chaperone, facilitating protein folding, preventing aggregation, and aiding in the refolding of misfolded proteins. In various pathological conditions, including neurodegenerative diseases, cancer, and cardiovascular disorders, HSP70 expression is often upregulated, indicating its role in cell survival and adaptation under stress. The study of recombinant HSP70/HSPA1B proteins has gained significant attention in recent years; researchers are focused on understanding its mechanisms in stress response and potential therapeutic applications. Recombinant technology allows for the production of large quantities of HSPA1B for in vitro and in vivo studies, enabling researchers to investigate its functions, structure, and interactions with other cellular proteins. Additionally, HSP70's immunogenic properties have prompted exploration into its use as a vaccine adjuvant and its role in cancer immunotherapy. By elucidating the diverse roles of HSP70/HSPA1B, researchers aim to uncover novel insights into its therapeutic potential, potentially leading to innovative treatment strategies for various diseases where protein misfolding and cellular stress are implicated.
